SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 619,170, dated February7, 1899.

Application filed June 20,1898. Serial No. 683,949. (No model.)

To all whom, it rncty concern:

Be it known that I, GEORGE H. HAMALIAN, a citizen of the United States,residing in Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Shuttles; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

My present invention relates to improvements in loom-shuttles,(especially for weaving narrow wears;) and its object is to provide sucha shuttle with sim ple bearings into which the spool or bobbinsupporting spindle can be readily and quickly inserted or liftedtherefrom and while in operative or normal position is prevented frommovement or accidental disengagement from said bearings, thus avoidingbreakage or undue tension on the spool or bobbin (weft) thread.

The invention consists in the improved shu ttle, its spindle-bearings,and the means for retaining said spindle in said bearings and in thecombination and arrangement of the various parts, substantially as willbe hereinafter more fully described, and finallyembodied in the clausesof the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several views,Figure 1 represents in a top plan view a ribbon-shuttle provided with myimprovements; Fig. 2, a sectional view on the line a: wolf Fig. 1; andFigs. 3 and a, sectional views on the line g 'y of Fig. 1, illustratingmodified forms of the spindle-bearings and the spindle-retaining means.

In said drawings, (t represents a shuttle provided in its nose or frontportion 1) with an eye I: and having a spring-controlled brake d,adapted to bear against the spool or bobbin, all of the usual andWell-known construction.

The spindle e for the spool or bobbin 9 (shown in dotted lines inFig. 1) has its bearings in a socket f and in the recess h,respectively, which latter communicates (see Figs. 1 and 2) with agroove 2', arranged in the inner portion of the shuttle-nose 5. Withinthe said groove is pivotally secured, as at m, a latch or block n,adapted when in normal position to engage with its lower portion 0 thetop surface of the spindle eto thus retain the latter within the recess71. A spiral spring 1) is provided for within the shuttle (in a suitablehole or socket) and is connected with the top portion of the fulcrumedblock n, and is designed to hold said block in normal position.

In connection with the above it must be remarked that a collar 1 ispreferably arranged on the spindle e and is adapted to bear against thefulcrumed block a to thus prevent undue lateral movement of the spindle.A notch q is furnished in the top portion of said block a forconveniently operating the samewhenever the spindle is to be removedfrom its bearings, as clearly illustrated in Fig. 2 of the drawings.

In the modification illustrated in Fig. 3 the bearing for the spindle eis furnished in the recess h at the terminal of the spiral orsubstantially J-shaped groove 2", which latter is arranged in the innerportion of the nose Z) of the shuttle a. A flat spring 19 is securedwith one end to a pin 1) projecting from the shut.- tle-nose, while itsother end bears upon the top surface of the spindle, as clearly shown insaid Fig. 3.

In the modification illustrated in Fig. 4 the spindle is retained withinits recess 71 by means of the curved end portion 19 of a flat spring 11which latter is secured with its opposite end to a pin p arranged in thegroove t and projecting from the shuttle-nose b.

In operation, reference being had to Figs.

1 and 2, whenever the spindle c is to be taken out of the shuttle theblockn is turned on its fulcrum against the action of the spiral spring19 into the position shown in dotted lines in Fig. 2, whereby the lowerportion 0 of said block is moved out of the path of the spindle, whichlatter can then be readily lifted out of said bearings, as will bemanifest. For reinserting the spindle into the shuttle one end of saidspindle is first inserted into the socket f and its opposite endthereafter slid into the recess h, the block nbeing turned to one sideby the spindle against the action of the spiral spring 19, which latteras soon as said spindle has seated itself in the recess h returns saidblock to its normal position. For removing the spindle from theshuttles, as illustrated in Figs. 3 and 4, the said spindle is simplylifted or moved out of its respective bearing, the spring 19 01- 9 beingpressed out of the path of the spindle, as will he manifest.

From the above it can be seen that in each and every constructionillustrated and described the spindle is firmly held in its operative ornormal position and is prevented from undue movement,and yet can bereadily and quickly lifted out of its hearings when necessary ordesired.

I do not intend to limit myself to the precise constructions shown anddescribed, as various alterations can be made without changing the scopeof my invention; but

What I claim as new, and desire to secure by Letters Patent, is-

v1. In a shuttle, the combination, with its nose provided on one of itsinner sides with a bearing and on its opposite inner side with a recessand connecting open groove, of a spool or bobbin carrying spindleremovably arranged in said bearing and recess respectively, and a blockpivotally mounted in, and controlling the passage through, said grooveto the recess, substantially as described.

2. In a shuttle, the combination with its nose provided on one of itsinner sides with a bearing and on its opposite inner side with a recessand connecting open groove, of the spool or bobbin carrying spindleremovably arranged in said bearing and recess respectively, and aspring-controlled block pivotally mounted in, and controlling thepassage through, said groove to the recess, substantially as and for thepurposes set forth.

3. In a shuttle the combination with its nose provided on one of itsinner sides with a hearing and on its opposite inner side with a recessand connecting open groove, of the spool or bobbin carrying spindleremovably arranged in said bearing and recess respectively, a blockfulcrumed within the groove and normally engaging the spindle butcapable of being moved out of the path of the latter, and a springcontrolling said fulcrumed hlock, substantially as and for the purposesdescribed.

4. In a shuttle, the combination, with its nose provided on one of itsinner sides with a bearing and upon its opposinginner side with a recessand connecting open groove, and a spool or bobbin carrying spindleremovably arranged in said hearin g and recess respectively, and apivoted transversely-arranged and spring-controlled spindle-retainingblock arranged in said recess,'substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this6th day of June, 1898.

GEORGE H. HAMALIAN.
